5.3 About Code Examples

This documentation contains simple code examples that briefly show how to use various parts of the device. These code

examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors

include bit definitions in the header file and interrupt handling in C is compiler dependent. Please confirm with the C compiler

documentation for more details.

5.4 AVR CPU Core

5.4.1

Introduction

This section discusses the Atmel AVR® core architecture in general. The main function of the CPU core is to ensure correct

program execution. The CPU must therefore be able to access memories, perform calculations, control peripherals, and

handle interrupts.
